How to Lock a VBA Macro

So far we developed various macros according to numerous requirements. So today I’m going to show you how to lock them with passwords. Because once you developed a macro you may want to lock it as it is your intellectual property. Also you may want to lock the project to protect it from being wrecked by other users.

So now let’s see how we can lock the project. Follow these easy steps. First open the Excel file containing the macro. Then click somewhere in the worksheet. Next press Alt + F11 on your keyboard. This will open the VBA editor.

Alternatively, you can go to the “Developer” tab and click on “Visual Basic” to open the VBA editor as well.

Note that the “Developer” tab is not displayed by default. This post explains how to add it to the ribbon.

How to show the Developer tab

As you can see in the first image, I have a very simple macro in the module1. To lock the project first click on the “Tools” menu.

Then select “VBAProject Properties...”

“Project Properties” dialog box will open. Go to the “Protection” tab and check the “Lock project for viewing”. Then enter the password in both textboxes and click OK.

Save the file, close it and reopen. Now when you go to the VBA editor and try to expand the project from project explorer it will ask you the password to unlock.

So if a user doesn't have a password then he/she can't view the code. But they can still run the macros from the developer tab. Thus anyone can run the macro without messing it up.

However if you want you can also protect the macro execution with a password too.

How to Add a Formula to a Cell Using VBA

In this lesson you can learn how to add a formula to a cell using vba. There are several ways to insert formulas to cells automatically.

Table of contents How to add formula to cell using VBA Add formula to cell and fill down using VBA Add sum formula to cell using VBA How to add If formula to cell using VBA Add formula to cell with quotes using VBA Add Vlookup formula to cell using VBA We use formulas to calculate various things in Excel. Sometimes you may need to enter the same formula to hundreds or thousands of rows or columns only changing the row numbers or columns. For an example let’s consider this sample Excel sheet.

Download a file from url using VBA

Sometimes our Excel VBA applications need to interact with websites. Downloading a file through a URL is a typical example. In this lesson you can learn how to do that using XMLHttpRequest and ADODB.Stream object. XMLHttp is used to request the data from the web server. Once we receive the data from the server, the ADODB.Stream object is used to write that data to a file. You can use this method to download file types such as image files, csv files etc. So let’s start writing our macro to download a file using the Uniform Resource Locator (URL). Let’s name our Sub procedure as “DownloadFileFromURL” Sub DownloadFileFromURL() End Sub First we need to declare a few variables. Dim FileUrl As String Dim objXmlHttpReq As Object Dim objStream As Object Next assign the URL of the file to the FileUrl variables FileUrl = "URL of your file" For an example if your file URL is https://www.example.com/images/chart.jpg then you can assig

Fill a Listbox From an Array

In this lesson you will learn how to fill a Listbox from an array. Listboxes are a very useful control type available in the VBA toolbox. You can use the listboxes for search and view functions of the VBA programs. First let’s fill the listbox using a multidimensional array. After that we can try it with a one dimensional array. This is the sample Excel sheet I’m going to use for this lesson. And here is the listbox we are going to fill with the array. So we have data in three columns and fourteen rows. First, we are going to add this data to an array. After that we can add the array to our listbox in the VBA form. You might wonder why we need to add the data to an array. Because data can be directly added to the listbox from the worksheet using VBA. Yes it is possible. But here our objective is to learn how to add data to a listbox from an array. Because there are situations where we need to add the data which is not available in worksheets to listboxes using VBA. For
